These are both excellent references. Here's what I'm looking to do. I
have a system at work that I'm testing this on. But more importantly.
If this works well, it will be pushed out and auto-executed globally to
2 to 3 systems per location.

Do you think I can use these references to make a single executable that
when launched from the administrators profile, or with the administrators
credentials. It can set these systems into auto login mode?

That wasn't really a contribution..

I am a bit scidish about the reference on MS that shows how to do this.

But it only talks about the account that you want to autolog, being an
administrator account.

Well, I don't want an administrator account to autolog, I want a regular
user account to autolog.

*EDIT* .. I got something working.. I'll post later.

LogonUser is not administror specific, it is up to you to choose who do you want to log as specified in the param, then, you should use ImpersonateLoggedOnUser with the value returned by LogonUser.

It's easy with admin rights and purebasic to write to registry. ( write values to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon : DefaultUserName / DefaultPassword / AutoAdminLogon ...

I've done this. But have experienced a major security issue. After I've
edited the registry settings. You cannot log into the system via RA
anymore. I know, wierd.

And to add to that pain, the auto log didn't work.

Keep in mind that the computer is on a domain. But the account that
I'm having auto log is a local account to the machine.

You can autologon to a domain with the 'DefaultDomainName' value.

Hey Droopy..

Yeah I have that. But it still didn't work. There must be something else
junked up on these systems. I even thoguht it might be the legal notice,
but as you can see I cleared those out. Hmm..

I haven't used PureBasic yet... Window shopping

But make sure you are setting all these values:

AutoAdminLogon
ForceAutoLogon
DefaultUserName
AltDefaultUserName
DefaultPassword
DefaultDomainName
AltDefaultDomainName

And LegalNotice/Logon Banner text won't stop it from working. To bypass the autlogon and get the prompt (for when you logon), hold down the shift key.

I do this sort of thing remotely in batch files using reg.exe i.e.

reg add "\\%strRemoteHostname%\HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon" /v ForceAutoLogon /t REG_SZ /d 1 /f

Edwin suggested a Sysinternals tools but didn't say which one. Here is a link to the program which may solve your problem:

http://www.sysinternals.com/Utilities/PsExec.html

It is very powerful and will allow you to run an app on a remote system with whatever credentials are needed.

psexec along with the other pstools are great, but he specifically wanted autologon... And you don't need 3rd party utils (or even PB) to make it happen local or remote.
